I am quite new to the hobby. I started this planted aquarium in late December of last year. It is a 32 gallon bio cube. I am running CO2. After a pretty serious trimming of the plants about a month ago, BBA started appearing. I’ve used Seachem and hydrogen peroxide, as well as removing as much of the BBA as possible. However, I have been unsuccessful. I would say that 60% of my plants have BBA on or in them. I’m starting to think if I should remove some of the plants and get new ones. I could just start hacking at the existing plants, but I don’t know how well they would recover. I could really use some advice. Thank you in advance to anyone who responds.
